can someone tell me where my Fe is with small words that I can understand

If you're an ISFj in Socionics, as is my wife, @Silent, then Fe is in your id under Model A theory. It's very powerful, and yet, as your ignoring function, you don't even notice when you're using it, and hardly notice when anyone else is using it either. My wife can calm a whole room full of people merely with her presence. She doesn't know how she does it. It just happens, and I've witnessed it on numerous occasions.

You don't seem to escape negative feelings to the land of hopes and enthusiasm like 7s do. You seem to understand the emotional negativity quite well and embrace it as a part of your self. I can see that you might try to escape them through acting like you don't really care, but this to me seems more like a part of your image and a persona you want others to see. Your avatars and self expression is very individualistic and you want to make it clear what sort of a person you are, which you express through evaluating your image focus.
